Unsafe for alkalinity dosingBy Phasezeroon 10/8/2013

I wouldn't recommend this for dosing your alkalinity. Out of no where mine turned on and started dosing the alkaline solution. I've had mine programmed and running for about a month. I was able to catch it early enough before any major damage was done thankfully. I wouldn't trust your whole tank with this unreliable timer.

I bought two of theses to dose Alk and Mg. They work as advertised. I noticed my Mg was gradually getting lower. I tried to override it in manual mode and sadly it did not work. So longetivity is questionable. But over all 4 stars out of 5. It is a good timer until I purchase an upgrade with a controller.

Bought an additional one to dose my Mg. Until you buy a controller like an Apex or Reefkeeper etc...this timer will do the trick. A little awkward to program but does the job. Always triple check your programming on these timers as they are not too intuitive to program. BRS, thank you.

Easy to set up and does a good job.By A. grandison 4/22/2013

I use one of these to dose from my kalk reactor during the night.
Never failed.
Only drawback is the clock, not so precise.
Minor problem, that's why I gave 4 stars.

I'm thinking to get 3 more and dose Ca, Alk and Mg for my new setup.
I'm considering this so I depend on individual timers for each feature, versus taking the chance and have a Reefkeeper falling all at once.

WARNING: Failure eminentBy Aaronon 12/23/2012

I brought 2 of these timers 5 months ago.

When I first received them 1 did not work. BRS promptly replaced.

After receiving my replacement, things worked great for the next 5 months.

AND THEN........

This morning while performing my monthly water testing, my calcium and alkalinity levels were way off. After investigation, I noticed that the timer running my alkalinity was broken. The clock was working, but it would not turn on. After replacing the battery, still not working. I think the internal relay is broken (it's mechanical). DO NOT buy this product, you will regret it.

It seems that there is no good/ cheap solution out there. Lucky thing I have enough money to buy a reefkeeper....

This product is great, I lose power from time to time and this has a battery backup that actually holds in what times I had set

Works great with no issues. separate dosing up to 8 times a day. Only problem is I dont know what I am going to do with it when I get a Ca reactor
